The tubular portion 22 has an inner diameter which is slightly smaller than the diameter of the opening portion 4 to which the opener 5 is opened, but which is larger than the outer diameter of the introduced treatment tool. For example, it has an inner diameter through which three sets of disposal tools having a diameter of about 5 [mm] can pass collectively. The length of the tubular portion 22 is the same as the thickness of the body wall 2. As the material constituting the treatment tool introduction portion 6, an elastic material such as polyurethane, polyvinyl chloride or polyethylene can be used.

As shown in Fig. 2, the string member T is fixed to the inner annular member 9 of the opener 5 at one end thereof, and is fixed to the fixing portion 25 of the handle member 8 at the other end. Further, the installation of the opener 5 with respect to the creating portion 4 is performed in a state where the string member T passes through the inside of the opener 5 and the tab member 8 is separated from the outer annular member 10.

The length of the string member T is set to be the shortest length that can be taken in the state in which the handle member 8 is disposed opposite to the starter 5 of the starter portion 4 and the handle member 8 is arranged as shown by the two-dot chain line in FIG. Has a sufficient margin.

In this configuration, when the patient is operated using the body cavity grasping and dispensing device 1, the starter 5 is first attached to the predetermined opening portion 4. That is, when the string member T passes the inside of the opener 5 and the tab member 8 is separated from above the outer annular member 10, the inner annular member 9 of the opener 5 is flexed and inserted into the body cavity from the priming portion 4. 3, and expand in the body cavity 3 It. Thereby, the inner annular member 9 is disposed on the side of the body cavity 3 of the rupture portion 4, and the outer annular member 10 of the ejector 5 is placed outside the body.

Then, the outer annular member 10 is gripped, and the opening member 11 is wound around the outer annular member 10 as a shaft, whereby the opening member 11 is radially expanded to form an opening having a diameter of a desired size, and the opening is made. The length of the member 11 corresponds to the thickness of the body wall 2. Thereby, the installation of the starter 5 is completed, and it is in the state shown in FIG.

Next, the handle member 8 is disposed on the inner side of the portion of the opening member 11 located outside the body so as to be substantially concentric with the outer annular member 10 or the opening portion 4. That is, the handle member 8 is disposed at a position as shown by the two-dot chain line in Fig. 2 .

Then, the treatment instrument introduction portion 6 is inserted into the ejector 5 . At this time, the tubular portion 22 of the treatment instrument introduction portion 6 is inserted into the opening formed in the initiation member 11. Thereby, the treatment instrument introduction portion 6 is in a state suitable for fitting a region from the outside of the body of the creator 5 to the portion of the nucleus portion 4. Further, the handle member 8 is fixed between the starter 5 and the treatment instrument introduction portion 6, and the string member T is passed through the opener 5 and the treatment instrument introduction portion 6 from the fixing portion 25 of the handle member 8. The state between the inner ring member 9 and the inner annular member 9 is reached again through the inner side of the opener 5.

Next, the two or three treatment tools arranged for surgery are passed through the closure portion 7 of the insertion portion 21, and are attached to the outer annular member 10. That is, the plugging portion 7 can be attached to the starter 5 by covering the outer annular member 10 with the mounting ring 13. This installation is to bundle the front end sides of each disposal tool and The tubular portion 22 of the treatment instrument introduction portion 6 is introduced into the body cavity 3 so that the distal end side is introduced into the body cavity 3.

According to the present embodiment, since the treatment instrument introduction portion 6 is composed of elastic material, the treatment instrument introduction portion 6 can correspond to the external force with high followability. Further, since the tubular portion 22 of the treatment instrument introduction portion 6 has a diameter through which the treatment tool 3 can collectively pass, the body cavity grasping device 1 can introduce, for example, two curved nose pliers into the body cavity 3 as a treatment tool. The degree of freedom of the insertion and extraction or the rotation of each curved nose pliers can be highly maintained.

Further, the plugging portion 7 has plural numbers even through the insertion portion 21 thereof. The airtightness can still be maintained when the support device passes, and it is not necessary to use the check valve of the casing to ensure airtightness. Therefore, the treatment tool can be directly introduced into the closure portion 7 without the need for a cannula. Therefore, the deterioration of the operability due to the mutual interference (entanglement) of the casing is not caused. Thereby, a plurality of disposal tools can be arranged close to each other via the sealing portion 7, and the operability of the treatment tool can be improved.

Further, since the treatment instrument introduction portion 6 is inserted into the ejector 5 before the closure portion 7 is attached to the ejector 5, even if the bending tool is used as the treatment tool, the treatment tool is inserted into the body cavity using the cannula. The same is true in the case of 3, which prevents damage to the creating portion 4 caused by the disposal tool. Moreover, damage to the rupturing member 11 caused by the treatment tool can also be prevented. Moreover, such an effect can be obtained only by a simple operation of inserting the treatment instrument introduction portion 6 into the ejector 5.

Further, in this case, compared with the case where a plurality of flexible sleeves composed of a plurality of types of materials or components are used, the treatment instrument introduction portion 6 which can be formed of one of the elastic material can be extremely low. The cost protection creation 4 or the creation of the component 11.

In addition, the handle member 8 which is used as a pull tab for pulling the priming member 11 together with the inner annular member 9 is fixed by the treatment tool introduction portion 6 after being placed on the erecting member 11, and thus is operated by surgery. During the period, the state of stability can be reserved in advance in its configuration position.

Further, in a state in which the body cavity pick-and-place device 1 is attached to the start-up portion 4, the handle member 8 is located outside the body in the starter 5, and the string member T is disposed from the inner ring member 9 through the start-up member 11 and The handle introduction portion 6 is passed between the handle portions 6 and reaches the handle member 8. Therefore, the rope component T is present in the seal Since the inside of the plug portion 7 and the starter 5 is not led out from between the treatment instrument introduction portion 6 and the closure portion 7 or the outer annular member 10, the airtightness achieved by the closure portion 7 is not caused by the rope. The component T is damaged.

In the eighth embodiment, the same constituent elements as those in the first embodiment are denoted by the same reference numerals. In the integrated cavity pick-and-place tool 34, the outer annular member 10 is used to pull the inner annular member 9 disposed on the side of the body cavity 3 of the opening portion 4 and pull the outer annular member 9 to be gripped.

As shown in Fig. 8, the string member T is fixed to the inner annular member 9 at one end, and is fixed to the fixing portion 25 of the outer annular member 10 via the inner side of the ejector member 11 at the other end. The length of the string member T is set to: The shortest length of the fixing portion 25 that is fixed to the inner annular member 9 from one end to the other end is fixed to the fixing portion 25 of the outer annular member 10 in a state in which the treatment instrument introduction portion 6 is inserted into the starter 5 attached to the opening portion 4. Has a sufficient margin.

When the body cavity pick-and-place tool 34 is attached and the starter 5 is attached to the starter 4, the inner annular member 9 is disposed on the body cavity 3 side of the fringe portion 4, and the outer annular member 10 is used as an axis to open the component 11 It was taken up. Along with this, the string member T is also taken up from the outer annular member 10 from the side of the fixing portion 25. Thereby, the remaining portion of the string member T that has not been wound up is in a state of extending to the inner annular member 9 via the inner side of the tapping member 11.

Then, when the treatment tool introduction portion 6 is inserted into the ejector 5 of the erecting portion 4, the remaining portion of the string-shaped member T that has not been wound is replaced by a portion other than the inner annular member 9 side. The state between the opening member 11 of the starter 5 and the treatment instrument introduction portion 6 is sandwiched.

When the opener 5 is removed from the erecting portion 4 in order to remove the body cavity accommodating device 34, the winding of the creator 11 with the outer annular member 10 as the axis is released, and the string member T is also along the starting member. The inner side of 11 becomes an extended state. Then, by moving the outer annular member 10 in the direction away from the blasting portion 4, the inner annular member 9 and the priming member 11 can be pulled out from the body cavity 3 via the string member T. At this time, since the string member T is often located inside the crevice member 11, the string member T does not damage the crevice portion 4.

Moreover, the string member T is mounted on the opening portion 4 in the body cavity pick-and-place device 34. In this state, the outside of the body cavity pick-and-place device 34 is not guided between the starter 5 and the plugging portion 7, and therefore the airtightness of the body cavity pick-and-place device 34 achieved by the plugging portion 7 is not deteriorated.

According to the present embodiment, since the outer annular member 10 can also be used as a grip member, the configuration of the body cavity pick-and-place tool 34 can be simplified. The other points are the same as those in the first embodiment of Fig. 1 .

The embodiments of the present invention have been described above, but the present invention is not limited by the embodiments. For example, the starter may be any one that can be attached to the plugging portion and the treatment instrument introduction portion, and may be a form in which the outer annular member is partially wound up.

Moreover, the handle member is not completely closed into a ring shape, and may be partially opened. In addition, the handle parts are not necessary for a perfect circle, and may also be polygonal or elliptical.
